Find Merchants and Clear Your Inventory
You’ll find that your inventory can fill up pretty quickly in Deus Ex: Mankind Divided, and yes, you do have a storage limit. Along the way, you’ll pick up tons of valuable items like Neuropozyne and various gyroscopes. These can take up quite a bit of space, and they don’t help you in battle. What you want to do is find a merchant who will buy all this junk off you for a good amount of credits. The game doesn’t explicitly tell you this, but if you pull up your map, you can activate the legend and look out for green icons with shopping carts on them. These indicate the locations of various merchants.
Merchants will sell different things. Some merchants specialize in hacking software, some in weapons, and some in consumables – but all of them will buy your useless items. Whenever your inventory fills up, make sure to stop by a merchant and unload all of your junk before setting off. It’s also a good idea to stock up whenever you can, too.
